2 To Better Understand: TODAY S OBJECTIVES Pavement Maintenance Prioritizing Projects and Pavement Condition Pavement Maintenance Management Program Pavement Classification Number (PCN) 2

3 HELPFUL TOOLS Advisory Circular (AC) 150/5380-7, Airport Pavement Management Program AC 150/5380-6, Guidelines and Procedures for Maintenance of Airports Pavements AC 150/5335-5, Standardized Method of Reporting Airport Pavement Strength (PCN) ODOT Web Site: 3

4 PAVEMENT MAINTENANCE 4

5 WHY PAVEMENT MAINTENANCE??? 5

6 PAVEMENT NOTES Most airport pavements: Do not fail because of load-induced damage. Are eventually destroyed by the elements: Most destructive element is excess moisture. If protected from weather induced damage, service life of pavement can be prolonged indefinitely. 6

7 PAVEMENT MAINTENANCE Maintenance is the most cost-effective way to extend pavement life. Retards Deterioration Proper Maintenance Management reduces total cost of system preservation. Pavement Maintenance Management Plan required for any rehabilitation/reconstruction project. 7

8 Prioritizing Projects and Pavement Condition 8

9 PRIORITIZING PROJECTS Demand for AIP funds exceeds availability. FAA bases distribution of limited funds on current national priorities and objectives. Higher priority = Higher consideration for funding. 9

10 NATIONAL PRIORITY RATING (NPR) Numerical model that is one of several tools FAA uses to prioritize airport development projects. First evaluation factor and serves to categorize airport development in accordance with agency goals and objectives. Yields the highest percentage of projects funded under the Airport Improvement Program (AIP). Generates values between 1 and 100, with a higher number indicating higher priority. NPR values for pavement rehabilitation projects range from 65 to

11 FAA POLICY For any project to replace or reconstruct pavement, sponsor must assure the airport has implemented an effective pavement condition and management program. 11

12 PAVEMENT MAINTENANCE MANAGEMENT PROGRAM (PMMP) 12

13 WHAT IS A PMMP? A Pavement Maintenance Management Program: Details procedures to assure that proper pavement maintenance, both preventative and reparative, is performed. Defines procedures for collecting, analyzing, maintaining, and reporting pavement data. Assists in finding optimum strategies for maintaining pavements. 13

14 PMMP BENEFITS Increases pavement useful life Provides an objective and consistent evaluation of the condition of a network of pavements. Provides a systematic and documentable engineering basis for determining M&R needs including consideration of future operational needs and/or planned airport expansion projects. Identifies budget requirements necessary to maintain pavement functionality. Provides documentation on the present and future condition of the pavements. Provides Life Cycle Cost Analysis for various M & R alternatives. Identifies impact on pavement if no major repairs are performed. 14

15 PMMP COMPONENTS At a MINIMUM, the PMMP should include: Pavement Inventory Location of all runways, taxiways, and aprons. Type of pavement Year of construction or most recent major rehabilitation. Dimensions. Inspection Schedule Detailed Inspection (must be performed at least once a year) If a PCI survey is available, the frequency of inspections may be extended to 3 years. Drive-by Inspection Should be performed a minimum of once per month to detect unexpected changes in pavement condition. 15

16 PMMP COMPONENTS (CONTD.) Record Keeping Complete information on findings of all detailed inspections and maintenance performed should be recorded and kept on file a minimum of 5 years. Types of distress, their locations, and remedial action, scheduled or performed, should be documented. Detailed Inspections - minimum information to be recorded: Inspection date Location Distress Types Maintenance scheduled or performed Drive-by Inspections - minimum information to be recorded: Inspection date Maintenance performed 16

17 PAVEMENT CLASSIFICATION NUMBER (PCN) 17

18 WHAT IS PAVEMENT CLASSIFICATION NUMBER (PCN)? Standardized Method of Reporting Airport Pavement Strength Aircraft Classification Number (ACN) ACN PCN 18

19 WHAT IS PAVEMENT CLASSIFICATION NUMBER (PCN)? Airport should have PCN calculated and published as part of runway rehabilitation/reconstruction projects. PCN applies only to pavements 12,500 pounds or greater. QUESTION?... ACN PCN Or ACN PCN 19
